Abstract
China has made remarkable progress in reducing schistosomiasis caused by Schistosoma japonicum over the past 7 decades but now faces a severe threat from imported schistosomiasis. Results from national surveillance during 2010–2018 indicate integrating active surveillance into current surveillance models for imported cases is urgently needed to achieve schistosomiasis elimination in China.

Because of enhanced international cooperation and communication, 2 Schistosoma species were identified from schistosomiasis cases imported to China: S. haematobium and S. mansoni
The Biomphalaria straminea snail, an intermediate host of S. mansoni trematodes, has been introduced into Shenzhen, Guangdong Province [3,4], so the possibility exists that imported S. mansoni trematodes could be transmitted to these snails and result in locally acquired human infections
